LATHE FOR IRREGULAR FORMS.

SPECIFICATION forming part of Letters Patent No. 347,036, dated' August 10, 1886.

Application filed April 1, 1886. Serial No. 197,383. (No model.)

.To'aZZ whom t may concern:

Be it known that I, WILLIM H. HAWLEY, of the city and State of New York, have invented an Improvement in Lathes for Irregu- 5 lar Forms, of which the following is a specification.

The object ofthis invention is to roughen or ornament the surfaces of billiard-cues and the handles of bats and other articles with .concave recesses in alternate positions in imitation of hammered work in metal. This character of work has heretofore been done by hand, and it is'very tedious and expensive.

I make use of revolving cutters with convex serrations adapted to the turning out of the concave recesses in the wood of the bat or billiard-cue handle, and I provide means for swinging the cutter-head out of action and moving the same endwise a distance equal to half the length of one ofthe serrations, and the handle is partially revolved the proper number of degrees, so that when the revolving cutter is again brought into action a second line of recesses is formed adjacent to the first, the concavities in one line being intermediate to those in the next line, and these operations are continued until the lines of recesses have been cut entirely around the handle, to both ornament Vand .roughen such handle.

In the drawings, Figure 1 is a plan View of the machine. Fig. 2 is an end view of the same, and Fig. 3 is a section at the line as x, Fig. 1. Fig. 4t is afront View of the machine.

The bed of the machine is formed of a plate, 3 5 A, supported on a suitable frame, and having near the ends the brackets B B, with journal boxes or bearings supporting the driving-shaft C, upon which is a pulley, D, driven by a belt.

The rotary cutter E is made of two or more blades, 2 2, secured upon the polygonal portion of a shaft, and the edges of these blades 2 are serrated or formed of convex scallops, and this rotary cutter is mounted in a frame, F,

' that is pivoted so that the said -frame can be` 45 swung and the rotary cutter moved toward or :from its work. I prefer to pivot this frame F upon the driving-shaft C, there beingeyes at the back ends of such frames, through which saidshaft C passes, and the power is commu- 50 nicated from this shaft C by the pulleys 8 and belts et to the pulleys 5 on the shaft of the rotary cutter.

The base-bar G lies against the plate A, and is fastened to the saine by the bolts 6, passing through elongated holes or slots, that allow the 55 said base-bar Gto be inclined to a greater or less extent, so as to bring the upper surface of a tapering handle or other article that is to be operated upon parallel with the axis of the rotary cutter E. Upon this base-bar G are 6o the head-blocks H K, that can be moved nearer together or farther apart and held by the clamp-screws 7. Upon the head-block K is a conical socket, L, upon an arbor, 8, in bearings 9, and there is a setscrew, 10, to support 6 5 the arbor 8 endwise. This conical socket L receives the end or head of the biliiardcue, handle, or bat, and said socket and arbor turn with the article that is being operated upon as said article is moved progressively iu the 7C" .manner next described.

Upon the head-block H are the bearings 40 11 for the tubular arbor M, the size of which is sufficient for the handle or other article to be operated upon to pass .through freely, and 7 5 at one end of this tubular arbor M is a clamp or chuck for centering and holding such handle or other article. I have shown the hinged clamps 12 and screw -ring 13 for forming the said chuck. Around the tubular arbor M is 8o a ratchet-wheel, 14, and there is a springpawl, 15, for holding the ratchet-wheel `arbor and the handle or other article while being operated upon.

The shaft 16 passes through bearings upon 8 5 the brackets B B, audit has at one end a handwheel, 17, by which it can be turned by the attendant. Upon this shaf t 16 is a double cam,

18, and this cam acts upon a projection or roller, 19, below the frame F. This cam 18 9o will raise the frame and rotary cutter off the work when in one position, or allow the said cutter to descend and perform the cutting whenin the other position. Upon this said shaft 16 is another cani, 20, that acts upon a 95 short lever, 21, the other end of which is within a groove around the shaft G,near one end thereof, and there is a third cam, 22, on the shaft 16, that acts upon the roller 23, slide-bar 24,

and spring-pawl2, that gives motion to the loo ratchet-wheel ll and tubular arbor M. The number of teeth in this wheel ll should correspond to or be a multiple of the innnber ol` ranges of indcntations to be cnt in the handle or other article, and the earns are shaped and placed so that when the handwheel 17 receives about a quarter rotation the traine F and cutter-head are raised from olf the work by the cani 1S acting upon the projection or roller lll, and at the salnetinie the cani 2l) acts upon the leverl, and shil'ls the driving-shaft (l and cutternhead cndn'isc a distance equal to halt' the length ol' one of the serrations or scallops, and as the wheel 17 is turned by hand to coniplete a hallrerolntion the cam 22, roller 253, slide-bar 2 l, and pawl 25 give to the tubular arbor NQ and the article held by the saine a partial revolution, and as the said hallrevolntion is completed the cani 1S allows thefranie F and cnttervhead to descend and en t the next row ol' concave recesses in the handle or other article, and these operations are performed successively until the entire handle is conipleted.

I elailn as my improvement l. A. ,rotaryeuttcrhaving blades with ranges of serratious upon their edges, anda trame lor supporting' the szune, in combination with headblocks and mechanism, snbslantiallyas specified, for supporting and rotating,|` progressively the handle or other article to be acted upon by the rotaryY cutter, substantially as set forth.

3. The tubular arbor M and (chuck, the socket li and arbor S, andthe respective headbloeks for supporting the parts, in con1bination with the adjustable base-bar carrying the head-blocks and the rotary cutter, the` drivingpulleys and belts, and the swinging frame that supports the rotary cutter, substantially as set forth.
